工作原理：

以氮氣為傳導傳熱介質，實現對制藥、生化、化工、生物等技術領域含有機溶媒、溶劑物料的干燥生產與溶媒、溶劑的回收，具備安全生產、高效、低耗節能減排的實用性。

干燥機內的氣體在風機（引風、送風兼用）的循環下，經換熱器加熱，由高效過濾器過濾后進入沸騰式加熱、干燥物料，熱風穿過物料的同時由內攪拌機構的不斷攪拌下使物料與熱空氣充分接觸換熱。待物料內的溶媒（酒精、丙酮、甲醇等）蒸發出來，在循環氣體的帶動下，夾帶于氣體中的細粉物料，經氮氣反吹除塵器，實現對夾帶于氣體中的粉塵物料進行捕集，余熱氣體經由過濾器過濾后進入冷凝器，經冷凝器冷卻介質，冷凝至露點和氣體分離，實現對有機溶媒的回收。分離后的氣體再由風機送入加熱器，這樣周而復始的循環工作。直至將所有的溶媒從物料中蒸發、分離、冷凝出來。

干燥后物料經過冷卻后從底部再排放出來，盛放物料的網板是由氣缸控制的可活動翻板。

物料排放完畢后，可用風機對干燥室內的過濾器進行清掃過濾。

Working principle:

Take nitrogen as medium for heat transfer, to realize solvent recovery and drying of material with solvent, with features of safety, high efficiency, Low energy consumption and so on.

Air under the circulation function of fan(both blower fan and suction fan),after heated by steam radiator and filtrated by HEPA filter, entry into fluid bed dryer to dry the material. At the meantime, under the continuous stirring of stirring system inside the dryer, hot air and raw Material exchange their heat fully. After solvent (alcohol, acetone, methanol and so on)steamed out, fine powder together with circulating gas come out, fine powder caught by nitrogen blowback system. Waste-heat air after filtrated by filter entry into compensator, solvent is cooled to dew point and separated from air, so solvent recycled. Separated air is fed into air heater by fan, go round and begin again like this..Until all solvent is steamed out, separate and recovered.

After drying, products are discharged from the bottom of the dryer, net plate for material is flexible reverse turning bed and controlled by cylinder.

After all products discharged, fan can clean the air filter inside the dryer.

設備的特點及優勢： Features and Advantage.

1.高效

設備為全封閉結構，無死角，出風、進風均采用高溫高效過濾，整個系統采用三級除塵，除塵效率更高，且易拆裝、清洗。在物料干燥完成后，使用反吹技術，除塵更徹底，減少清洗頻率，操作簡單，有效降低勞動強度并可避免產品受污染的情況，符合GMP要求。

設備能夠長期穩定的連續運行，自動化程度高。既可干燥、冷卻溶媒，又可冷卻物料，干燥效率比回轉、耙式的高，可提高4~5倍的干燥速度，同時干燥后的產品品質穩定，為用戶創造更大的產品價值。

根據客戶需要，可配備真空上料、出料，提高一體化智能操作。

2.安全

基于有機溶劑具備易爆易燃的安全危險性，本機組系統內同時采用在線測氧、超壓泄放和防爆、泄爆等安全技術手段，通過智能化控制技術，實現對系統內氧氣殘留量的監測，氣壓平衡監測和自動調節控制。當系統內的空氣（氧氣）含量超過0.5%（v/v）時，測氧裝置即會通過控制系統指令氮氣補充閥打開，向系統內補充新鮮氮氣，使系統內的氧氣殘留量恢復到安全設定值的范圍內（閉路循環系統設計為正壓，氧氣的進入則是通過加料過程進入循環系統）。當系統內的氣壓值超過設定值時（循環系統氣壓平衡值設定為0.02mPa），泄壓裝置則會通過智能控制中心指令，自動打開泄壓氣動閥，排除超壓氣體，而防爆泄爆裝置，則是本機組采用的另一項安全技術措施，即系統內電氣或關鍵部位發生故障，系統正常工作失靈，氣壓升高至安全極限值（系統設計耐壓值小于等于0.05Mpa），防爆泄爆裝置即會自動打開定向泄爆并自動切斷電源，關閉進出管道閥門，保證溶媒沒有與氧氣反應的可能性，有效的避免設備在生產過程中發生火災或爆炸事故，^大限度的規避人員傷亡和財產損失，確保生產安全.

3.節能.

設備是全封閉式系統，熱介質經過網板向上吹起物料，與物料的接觸更充分，使傳熱和傳質過程得以強化，在較小的風量下能夠達到較高的氣體含濕量，因此工作時只需要微正壓，風量較小，設備的風機功率降低，噪音變小，同時干燥之后含有溶媒的熱濕氣，經過冷凝器分離后，回收的溶媒可以再次利用，同時，低露點的氮氣經循環風機后進入加熱器重新加熱循環利用，與常規烘干設備相比，熱效率提高了，動力消耗明顯下降，因此節約了設備的能源損耗及生產成本。

4.環保

本機組實現對含有溶媒物料在干燥生產工藝過程中的回收利用，在解決相關行業在干燥難與廢氣排放污染重的基礎上，實現溶劑回收利用，同時做到零排放，避免了尾氣對環境的污染，獲得節能減排的實用性效果。

1.High efficiency.

This machine is fully enclosed structure, no dead corner, both air exhaust system and air in system takes high-temperature and high-efficiency filter. The whole system has 3 levels of dust catcher, with high-efficiency dust catcher, easy to discharge and clean. After drying finished, because of blowback system, dust elimination is more thoroughgoing, reducing cleaning frequency, which can reduce labor intensity and avoid pollution of different products, Low viscosity, meeting GMP standards.

This machine can work continuously and steady in a long term, high degree of automation. It not only can dry, cool solvent, but also can cool raw material, drying efficiency is higher than other dryer, 4 to 5 times drying speed. And, the finished products have good quantity, which can create bigger product value for the user.

According to the user’s requirement, vacuum feeder, vacuum discharger for optional, to enhance automatization degree.

2. Safety.

Because of flammable and combustible dangerous of organic solvent, this machine take Safety technologys including on-line Oxygen checking, explosion-proof, Explosion venting and so on. Through intelligentized control technology, to monitor Oxygen residues/Pressure balance in the system and automatic modulation control. When air(oxygen) content exceed 0.5%(v/v),oxygen checking device open the Replenishing valve to supply fresh nitrogen by control system, to recovery the oxygen residues to a safety value(closed-circuit system is designed into positive pressure,oxygen entry into circulation system by material feeding).When air pressure inside the system exceed setted value(air pressure balance is setted into 0.02mpa),explosion venting device will automatically open decompression Pneumatic valve to exhaust some air by intelligentized control .The explosion-proof and explosion venting system is another safety technology of this machine, that is when certain electrical equipment or key device damaged, the system is out of normal working and air pressure up to safety ultimate value(≤0.05Mpa),explosion-proof and explosion venting system will be automatically opened, power cutted off and pipe valve closed, there is no probability of solvent reacting with oxygen,which avoid fire damagesor explosion during machine working.to make sure safety production.

3. Saving energy.

This machine is full closed system. Hot air through net board blow up the material. Hot air contact with material fully. The process of heat transfer is enhanced. At a Few air condition, a high air moisture can be got, so Only Micro positive pressure during working, needed air quantity is small. Fan power of this machine is smaller and less noise. At the meantime,

Hot air with solvent after drying is separated by condensator. The recoveryed solvent can be reused. So saving energy and production cost. Also, Low dew point nitrogen is sent to air heater for cyclic utilization by fan. Compared with common dryer, thermal efficiency enhanced, power consumption reduced, so heat consumption and production cost saved.

4.Environmental protection.

This machine recovery the solvent from raw material during drying process based on solving the problem hard drying and Heavy pollution. At the meantime, zero exhaust avoid environmental pollution because of waste gas.
